You can create as many elements as needed by right-clicking the element that you
want to use as parent. You can drag and drop elements to move them in the structure,
and you can also cut, copy, and paste them. Additionally, you can copy schema columns
from
Talend Studio
component schemas or from the Generic Schema Editor and paste them into your
structure. For more information, see
